5 combos

Ethereal Weapon S StrongTech

Ethereal Weapon + Duskblade. After upgrading W, one hit procs all plasma stacks.

Use new Mystic Punch's all-ability CDR with Runaan's split shots (also procs the hex), plus Dusk and Dawn double-proc — one auto reduces all CDs by 5s, enabling infinite Icathian Rain. Core is Mystic Punch + Runaan's combo; you have to actually hit.

Ethereal Weapon S

Use Ethereal Weapon so abilities carry on-hit + Dusk and Dawn's Sheen damage — evolved W detonates 5 plasma stacks at long range. Must evolve W; vs tank teams swap Shadowflame for Void Staff; if you want to evolve E, grab Berserker's Greaves.

Critical Healing S

Infinite missiles. Tech gun + crit = bloodlust build.

Use Marksmage + Zealot's AP scaling for mixed damage. A mage-side meme build.
